My 2020 Gila monster season is off and running. After reviewing my data and re-reading my Gila books, I was going to wait until after April 1 this year to pair the Gilas as that is when the magic happened (and seems to be for others as well). With the Shelter-in-Place order in full effect I got bored and but them together last weekend, and guess what? No activity yet. What I have found interesting is that the Gilas seem to remember each other from last year and there was no fighting between the pairs (females bit males for being too pushy). This year they are much more chill, and are spending time together the hide boxes. I have been checking in at night to see what is going on and while both Gilas are active, copulation has not yet been observed. Being a Nervous Nelly, I am concerned that they will not breed this year but will hold my real worry for late April
To me, the real question is could Gila monsters mate for life? I’ve read that in the wild males go back to the same shelters where they have previously copulated and in my observations females certainly do prefer some males over others. The way they rest together and spend time with each other makes this is an interesting avenue to explore. Some breeders swap different females in male cages and have great success, but I am going to try leaving known pairs together to see how things go. I can see why having one pair of Gilas could be difficult to breed and that groups (3.3 or greater) are suggested.
As with all things, time will tell. New observations, and hopefully some activity, will be reported here. Stay tuned..
